Progress scores are calculated for each child by looking at all children who achieved the same level as them in Year 2 (end of KS1) and comparing their Year 6 result to the average for this group. The school average is then calculated by taking the average score for the whole Year 6 cohort.

A score of 0 represents a child making the expected level of progress. Positive scores above this are better than expected and negative scores below this are less than expected progress. Scores between -5 and +5 are considered the normal range.
